Abstract
The invention discloses a spreadlight lens of an LED street lamp, which comprises a lens body, wherein a quasi-spherical inner cavity for LED lamp beads to be placed is arranged on a bottom plane of the lens body; a light incident surface of the lens is formed on the bottom plane of the lens body; the back side of a bottom plane where the light incident surface exists is a light emergent surface; and a warpage for reflecting the light emitted by the light incident surface is arranged on the edge of one side of the lens body. The invention can be used for effectively projecting the light to a motorway in the LED street lamp application without adjusting the pitch angle of the street lamp, is convenient to use and can effectively overcome the defects of inconvenient adjustment and light pollution of the lens in the prior art.
Description
Technical field
The present invention relates to a kind of lens, especially a kind of spreadlight lens with the LED street lamp.
Background technology
Street lamp is the important component part of road lighting, traditional street lamp often adopts high-pressure mercury lamp, the high-pressure mercury lamp shortcoming that light efficiency is low has on the whole caused the huge waste of the energy, therefore, the LED street lamp as a kind of new and effective, energy-conservation, the life-span is long, colour rendering index is high, the street lamp of environmental protection and being widely used in the city illumination engineering.In the practical application of LED street lamp, people often need to install a secondary lens again in order to obtain suitable distribution of light and illumination brightness on LED lamp pearl.Yet, being limited to the structure of secondary lens in the prior art, the light that LED lamp pearl sends has the light of quite a few to project on the walkway through perpendicular projection.This has not only dwindled the motor road illumination zone, has also reduced the uniformity coefficient of car lane illumination, affects easily traffic safety.Traditional solution is to adjust the light fixture elevation angle, but this method then can cause inconvenience is installed, and affects attractive in appearance.And this lens also can cause certain light pollution.
Summary of the invention
For addressing the above problem, the invention provides a kind of light chopping lens that can concentrate projection LED lamp pearly-lustre line.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of LED street lamp spreadlight lens, comprise lens body, described lens body base plane is provided with the class spherical inner chamber of putting into for LED lamp pearl, it forms the incidence surface of lens, the reverse side of the base plane at described incidence surface place is exiting surface, and a lateral edges of described lens body is provided with the warpage that light that incidence surface is penetrated reflects.
As improvement of the technical scheme, a side that is positioned at warpage in the described class spherical inner chamber be provided with relative with warpage and with base plane substantially vertical enter optical plane.
As further improvement in the technical proposal, described warpage is formed by the spherical arc transition of some sections different curvature or same curvature.
As further improvement in the technical proposal, the both sides relative with entering optical plane are provided with for the groove that cuts light on the described lens body.
As further improvement in the technical proposal, also be provided with mounting structure on the described lens body.
As further improvement in the technical proposal, described mounting structure is the register pin that is symmetricly set on the lens body side.
Beneficial effect of the present invention: when the light that sends when led light source is refracted to lens warpage position by spreadlight lens class spherical inner chamber incidence surface of the present invention, make the light generation total reflection that projects the lens afterbody, thereby realize light not reflect the lens afterbody and all be reflected back effect in the lens, the light that is reflected back lens throws away by exiting surface again, can form specific light spot shape towards a side of lens exiting surface.Can be effectively in the LED street lamp application with ray cast to car lane, thereby do not need to adjust the angle of pitch of street lamp, use very conveniently, can effectively solve lens exist in the prior art adjustment inconvenience, have the defective of light pollution.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is perspective view of the present invention;
Fig. 2 is that lens of the present invention are looked up structural representation;
Fig. 3 is lens perspective structure synoptic diagram of the present invention.
Embodiment
Referring to figs. 1 through Fig. 3, a kind of LED street lamp spreadlight lens of the present invention, comprise lens body 1, described lens body 1 base plane 11 is provided with the class spherical inner chamber 2 of putting into for LED lamp pearl, it forms the incidence surface of lens, the reverse side of the base plane 11 at described incidence surface place is exiting surface 3, and a lateral edges of described lens body 1 is provided with the warpage 4 that light that incidence surface is penetrated reflects.When the light that sends when led light source is refracted to lens warpage 4 position by spreadlight lens class spherical inner chamber 2 incidence surfaces of the present invention, make the light generation total reflection that projects the lens afterbody, thereby realize light not reflect the lens afterbody and all be reflected back effect in the lens, the light that is reflected back lens throws away by exiting surface again, can form specific light spot shape towards a side of lens exiting surface.Can be effectively in the LED street lamp application with ray cast to car lane, thereby do not need to adjust the angle of pitch of street lamp, use very conveniently, can effectively solve lens exist in the prior art adjustment inconvenience, have the defective of light pollution.
As preferably, a side that is positioned at warpage 4 in the described class spherical inner chamber 2 be provided with relative with warpage 4 and with base plane 11 substantially vertical enter optical plane 21.Like this, enter that optical plane 21 can concentrate with light refraction to warpage 4 positions, more light can be reflected.
Wherein, bright dipping aspect according to actual needs, the angle between warpage 4 and the lens base plane 11 can be adjusted.If warpage 4 is divided into upper and lower surface, then the lower surface of warpage 4 belongs to optical cross section (light only reflects in this optical cross section), this optical cross section is determined according to incidence surface, can with base plane 11 angled being obliquely installed, thereby reach the present invention with the purpose of ray cast to the car lane.Warpage 4 upper surfaces then belong to exiting surface (light mainly reflects at this face), the exiting surface of warpage 4 is to determine according to the optical range that goes out of optical cross section and actual needs, so the actual angle of warpage 4 can design and adjust according to the optical range that goes out of incidence surface and actual needs.
In order to reach different light distribution effects, as preferably, described warpage 4 is formed by the spherical arc transition of some sections different curvature or same curvature.
In addition, in order to reach the purpose of cutting light, both sides relative with entering optical plane 21 on the described lens body 1 are provided with groove 5.
As preferred implementation, can mounting structure be set in lens body 1, be installed in the road lamp bracket with convenient spreadlight lens with this product.Further, described mounting structure is the register pin 12 that is symmetricly set on lens body 1 side, and structure is very simple, is convenient to make.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of spirit of the present invention, the modification that these are equal to or replacement all are included in the application's claim limited range.
